NHEB(i) 19 and it shall be with him, and he shall read it all the days of his life; that he may learn to fear the LORD his God, to keep all the words of this law and these statutes, to do them; 20 that his heart not be lifted up above his brothers, and that he not turn aside from the commandment, to the right hand, or to the left: to the end that he may prolong his days in his kingdom, he and his children, in the midst of Israel.
